Easily anchored mitre boxes

ABSTRACT

A channel-form wooden mitre box whose front wall member extends a bit below resting surface, has front-to-back through-holes near each side end passing through the bottom wall member, in which holes are slidable, rotatable shanks carrying a washer behind a wingnut at their threaded front ends which extend forwardly of the box structure, and said shanks are bent at their rearwardly extending ends to provide lateral extensions, which may be straight pieces or hook-forms. The downward extension of the front wall member and said rear lateral extensions of the shanks, serve as the jaws of a clamp, upon tightening the wingnuts. For the straight pieces, a tabletop is provided with two spaced holes to receive them. For the hook-forms, a wooden block is secured atop a table or two nails are driven into the tabletop in spaced relation, for the hooks to engage.

The downward extension of the front wall member and said rearlateral extensions of the shanks, serve as the jaws of a clamp, upontightening the wingnuts. For the straight pieces, a tabletop is providedwith two spaced holes to receive them. For the hook-forms, a woodenblock is secured atop a table or two nails are driven into the tabletopin spaced relation, for the hooks to engage.

EASILY ANCHORED MITRE BOXES The present invention relates to and itsprincipal object is to provide a novel and improved wooden mitre box ofchannel form which can be easily anchored onto a table and may beprovided with a simple work-holding means, all for the convenience ofhobbyists, home craftsmen, and in carpentry generally, to eliminate theusual practice of holding a mitre box by hand against a table edge andusing a finger of such hand to hold the work while the saw ismanipulated by the other hand.

Another object thereof is to provide a novel and improved mitre boxconstruction of the character described, utilizing ordinary channel-formwooden mitre boxes, which I equip with fittings which give them theadvantage of this invention.

A further object thereof is to provide a novel and improved easilyanchored mitre box having the mentioned attributes, and which is simplein construction, reasonable in cost to manufacture, and efficient incarrying out the purposes for which it is designed.

Other objects and advantages will become apparent as this disclosureproceeds.

For one practice of this invention, an upright channel-form wooden mitrebox is provided near each side end with a through hole front to back. Ineach hole is a slidable shank having an outwardly extending threaded endcarrying a washer behind a wingnut, while its outwardly rearwardlyextending end is bent downwardly to form said shank into an L- shape, oras in another embodiment shown, said rearwardly extending end is bent tomake it a hook-form. For the L- shapes, a tabletop is provided with twoholes in proper spaced relation from the tables front edge to receivethe downward portions thereof. For the hook-shapes, an elongated woodenblock is secured atop the table. A work-holding J-bolt using a wingnutforward of a washer, may be provided through the midupper region of thefront wall.

In the accompanying drawing forming part of this specification, similarcharacters of reference indicate corresponding parts in all the views.

FIG. 1 is a perspective view showing a mitre box prepared to be fittedwith anchoring means in accordance with the teachings of this invention.

FIG. 2 is an enlarged end view of a mitre box embodying this invention,shown mounted on a table provided with a wooden block secured thereon onwhich the box is rested.

FIG. 3 is a fragmentary perspective view of the table and said block.

FIG. 4 is an enlarged end view ofa modified embodiment of thisinvention, shown mounted on a table provided with two holes speciallypositioned.

FIG. 5 is a fragmentary perspective view of the table having said holesthrough its top.

FIG. 6 is an enlarged fragmentary view, shown in section, of a holestructure and the shank therethrough. This view which is in perspective,shows another manner of mounting the mitre box of FIG. 2.

In the drawing, the mitre box designated generally by the numeral 15, isan upright wooden channel-form extending from left to right, having arear wall 16, a bottom wall 17, and a front wall 18 extending a bitdownwardly below the bottom resting surface 17' of the box, to provide askirt 19, which is to rest against a vertical surface while the boxrests on a horizontal surface. The work 20 to be cut by a saw setthrough a pair of companion slots 20, 21', or 21, 21, or 22, 22', isrested within the box lengthwise on the upper surface 17" of the bottomwall 17, and against the rear surface 18 of the front wall 18. Thismitre box, near each of its ends, has hole structures below the uppersurface 17" of the bottom wall 17, opening at the front and rearsurfaces of the box. These hole structures are preferably through-holeswhich are through the bottom wall 17 and extend to the surfaces of thefront and rear of the box. Each of these holes, indicated by thenumerals 23, carries a slidable shank 24, whose outwardly forwardlyextending end is threaded as at 24', and whose outwardly rearwardlyextending end is bent downwardly to form with the shank, an L-shapebolt, indicated generally by the numeral 25, or a hook-shape bolt,denoted generally by the numeral 26. To hold the work 20 while it isbeing cut, a J-shape bolt 27, may be provided as shown through a hole28, in the midupper region of the front wall 18; such bolt having awingnut 29 behind a washer 30 on its outwardly forwardly extendingthreaded end 31, and a rubber tip 32 on its end which is inside themitre box. The threaded forward ends of each of the bolts 25 and 26,also have a washer 33 behind a wingnut 24.

To securely mount the mitre box construction of FIG. 2, an

elongated block of wood 35, is nailed on a tabletop 36, along the tablesfront edge, to support the box so that its skirt I9 is against the frontface of said block and the hook portions of the bolts 26 are behind saidblock. Then as is evident, the wingnuts on the hook-shaped bolts 26 aretightened so the pointed ends 24' bite into said block as is shown insaid FIG. 2.

To securely mount the mitre box construction of FIG. 4, two holes 37 aredrilled in a tabletop 38, to loosely admit the downward pieces 39 of theL-shaped bolts 25, when the skirt 19 is against the front edge ofthetable. Then as is evident, the wingnuts on said bolts are tightened,which is the condition shown in said FIG. 4.

Another way to mount the mitre box of FIG. 2, is shown in FIG. 6, wherethe hook bolt 26, which may be called a J-shape bolt, is turned to liein a horizontal plane to engage a nail 33, or it may be a wooden peg,driven into the tabletop.

In all the constructions and manners of use shown, it is evident thatthe downward extension 19 of the front wall member and the lateralextension at the rear end of the shank, serve asjaws ofa clamp to mountthe mitre box.

This invention is capable of numerous forms and various applicationswithout departing from the essential features herein set forth. It istherefore intended-and desired that the embodiments shown herein shallbe deemed merely illustrative of the teachings of this invention.
